cardio 3 Flashcards
white clot syndrome, associated with increased use of heparin,
heparin induced thrombocytopenia and thrombosis
what does the spleen do with blood
removes old and defective RBCs from circulation, returns iron from Hgb to bone marrow for reuse, storage for platelet mass (30%)
malignant change in lymphocytes causing tumors in lymphoid tissue
lymphoma
disease in which gastric mucosa is not secreting IF bc of antibodies being directly against the gastric parietal cells and or IF itself
pernicious anemia
what populations are affected by iron deficiency anemia
pregant, menstrating women
infants, children adolescents
those with poor diets
cardiac output =
stroke volume x HR
one of the most common hematological disorders world wide
iron deficiency anemia
what begins the clotting process
platelets
disease confined to only one lymph node or region
Stage I
thr force exerted by the blood against the walls of blood vessels
blood pressure
painless moveable enlarged lymph nodes on one side of the body
hodgkins lymphoma
if a pts hemoglobin is below 8 what must be done
place pt on 3 liters via NC
what blood product would you need to control or prevent bleeding caused by thrombocytopenia
(30-50ml bag infused over 30-60 minutes)
platelets
carry fluid to lympatic duct or thoracic duct
lymph capillaries
what system works through diffusion and carries fluid from interstital space to blood, preventing edema
lymph system
known as “silent killer”
HTN
filter bacteria and foreign particles
lymph nodes
how do the kidneys assiste with BP control
by regulating sodium and fluid volume
charcterized by debilitating fatigue with a variety of complaints
chronic fatigue syndrome
abnormal destruction of circulating platelets
immune thrombocytopenia puroura
normal lifespan is 8-10 days with ITP 1-3 days, destrucion exceeds production
what is given for Lymes disease
amoxicillin po 2-3 weeks
normal WBC count
4-11
Rh+ can
receive any blood
the spleen produces what during fetal development
RBCs
drains into subclavin vein
lymph duct
arterial BP =
CO x systemic vascular resistance
when you have a HTN emergency what do you not want to do
lower BP too quickly, decrease mean arterial pressure by no more than 25% inone hour
over production and accumulation of functionally inactive lymphocyte due to genetic mutation
chronic lymphocytic leukemia
Rh-cannot recieve
+ blood
normal hematocrit
women 38-47%
men 40-54%
what blood product whould you need to increase O2 carrying capacity without volume (most common)
RBC
occurs in bone marrow, liver and slpeen.
hemolysis, erthrocyte destruction
what is associated with under production of RBCs and decrease of survival of the RBCs
anemia of chronic diseses, RBCs survive less than 120 days
group of disorders characterized by large and abnormal RBCs
megaloblastic anemia
what is the most common site for a bone marrow study
posterior iliac crest
Hgb 6-10
moderate anemia
tachycardia, dyspnea, diaphoresis, pallor
if you have a decrease in BP that activates what
sympathetic nervous system
excessive bone marrow production of erythrocytes, leukocytes and platelets which results in increased blood viscosity and volume
polycythemia
megaloblastic anemia is due to
vitamin deficiencies such as Vit B 12 and folic acid
signs and symptoms of polycythemia
pruitus, increased clotting, enlarged liver and spleen, bleeding, GOUT, CVA
the reduction of platelets below level needed for normal blood clotting (below 150,000)
thrombocytopenia
what WBC is first to arrive at the injury site, an increase of these could mean infection or tissue injury
neutrophils
if you are Rh+ you can donate to and receive from?
donate to RH+
recive from Rh+, Rh-
usually ABO incompatibility
acute hemolytic
Hgb less than 6
severe anemia
hypotension, heart failure
immature RBC
reticulocyte, they mature in 48 hours to a erythrocyte
what is the dagnosis of hodgkins
biopsy with reed sternberg cells
how is lymphoma staged
with roman numeral I-IV (which reflects location and extent) and with A or B ( either absence of or symptoms present)
enlarged spleen, decrease of RBCs, WBCs, and platelets
splenomegaly
folic acid deficiency is very common and folic acid is needed for what
normal DNA synthesis of erythropoiesis
lymohangitis
inflammation of one or more lymphatic vessels, often seen in arms or legs
what gives protection from invading organisms
WBCs (leukocytes)
what are the two major compoents of blood
plasma, blood cells
blood administration process
baseline VS (within 15 minutes)
check PT ID
begin slowly (50ml/hr for 1st 15 min then incrsae to 125ml/h)
monitor pt q15initially then once/hr
transfuse in less than 4 hours
flush line with ND & d/c
complete paperwork
transfusion report to blood bank
relaxes vascular smooth muscle producing vasodilation
vasodilators
what WBC is formed during allergic response to allergen
eosinophils
what WBC is responsible for immune response, B cells and T cells
lymphocytes
what is the most characteristic sign of lyme
erythema migrans (bulls eye rash)
impaired production of RBCs, bone marrow is severly hypocellular, pancytopenia develops
aplastic anemia
decrease in total WBC count
leukopeina
what medication for HTN is not prescribed for patients with respiratory disorders
non selective beta blockers
what is the most commonly occurring hematologic cancer
non hodgkins lymphoma
sustained elevation of BP over 140/90 or use of anti-hypertensives in adults over 18y, average of 2 or more BP properly measured while sitting on at least 2 visits
HTN
what does the RAAS (renin angiotensin aldosterone system) do
decreases blood flow thorugh kidneys (holds onto sodium and H2O which increase blood volume and increase cardiac output
reticulocyte count measures
the rate at which RBCs appear in circulation
diease involving node on both sides of the diaphragm
Stage III
pancytopenia
low count of RBC, WBC and platelets
in the endocrine system, the stimulation of the SNS stimulates the release of epi/norepi which does what
increases HR & myocardial activity (CO) and causes vasoconstriction
